    hey guys i have a 2019 XLT with 5800 miles. i started noticing when shifting from park to reverse i hear a cluncking noise. only happens from park to reverse. it happens on flat ground or a incline. Any ideas?

    Do you set the parking brake before you remove your foot from the brake?

    I only have a thump if I don’t use the parking brake. I now use it 100% of the time.

    If its when you first start the car in the morning, the engine is cold and is high idling sometimes. That hi idle going into reverse slams in much harder than after it idles down when warmed up.
    just a thought.

    Unfortunately, this is a known quirk of the ford sourced 10 sp. Its starting to show up in the explorer aviator cars as well

    I have the clunk occasionally. If you wait 2 minutes after cold start or 30 seconds after warm start, the rpm will drop to 600 and you get noticeably lower clunk.
